TORONTO (AP) – Police have fanned out across more than a dozen crime scenes after a rampage by a gunman disguised as a police officer left at least 18 dead and homes in smoldering ruins in rural communities across Nova Scotia. The weekend attack was the deadliest in Canadian history. Among the dead were a policewoman and the suspected shooter. Officials identified the suspect as 51-year-old Gabriel Wortman, and say he drove a car made to look like a Royal Canadian Mounted Police cruiser. Authorities did not provide a motive for the killings, but say they believe he acted alone.
